Full title: Synthesis, X-ray structure, and reactivity of (NBu4)2[Pt2(μ-C5F 5)2(6F5)4]·H 2O and (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4O(C2H 5)2]. The first complexes containing bridging pentafluorophenyl groups. By reacting (NBu4)2[Pt(C6F5)3Cl] with AgClO4 (molar ratio 1:1) in CH2Cl2/diethyl ether, the binuclear complex (NBu4)2[Pt2(μ-C6F 5)2(C6F5)4] (1) is obtained. (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4]·O(C 2H5)2 (2) can be prepared by reacting 1 with AgClO4 (molar ratio 1:1) or by treating (NBu4)2[Pt(C6F5)3Cl] with AgClO4 (molar ratio 1:2) in CH2Cl2/diethyl ether. Complex 2 reacts with neutral monodentate ligands (L) yielding (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4L] (L = PPh3, 3; L = CNCy, 4). The structures of the binuclear platinum complex 1 and the trinuclear Pt2Ag complex 2 have been solved by single-crystal X-ray diffraction. Complex 1 contains the platinum atoms bridged by pentafluorophenyl groups (Pt-Pt distance = 2.714 (1) A?). Complex 2 contains two Pt-Ag bonds unsupported by other covalent bridges (Pt-Ag distances = 2.815 (2) and 2.804 (2) A?. The platinum atoms (Pt-Pt distance = 2.687 (1) A?) are bridged by two pentafluorophenyl groups and one silver atom.
